The Dexter Industries Thermal Infrared Sensor reads surface temperatures of objects. It is a non-contact thermometer based on the MLX90614. Detecting the infrared radiation from an object, the sensor can read object temperatures between -90°F and 700°F (-70°C and +380°C). The sensor has a high accuracy of 0.5°C and a resolution of 0.02°C.

The Thermal Infrared Sensor reads both the ambient temperature (the temperature of the air around the sensor) and the surface temperature of the object that the sensor is pointed towards.
